Galvanized Steel Purification Doors for Cleanrooms

Our purification doors strictly adhere to mainstream international cleanliness standards, including the FDA Food and Drug Standards, EU CE Certification Regulations, and ISO 14644 Cleanroom Classification Standards. From material environmental friendliness to performance parameters, they have all been tested by authoritative European and American institutions. Whether it is the aseptic requirements of pharmaceutical workshops or the microdust control in semiconductor factories, our doors can perfectly adapt, enabling your production and operation to fully comply with local regulations and avoid compliance risks.

In response to the usage environments and industry demands in Europe and America, we have adopted high-standard steel configurations for the door structure:

1.The door frame is made of 1.2MM galvanized steel sheet: Thanks to the thicker sheet thickness, the overall load-bearing and anti-deformation capabilities of the door frame are significantly enhanced. Even in industrial scenarios with high-frequency use, it can maintain structural stability for a long time, extending its service life.

2.The door leaf is made of 0.8MM galvanized steel sheet: While ensuring the strength of the door leaf, the precise thickness design achieves lightweighting. When paired with high-quality hinges, the door opens and closes more smoothly and with less effort, and it can also reduce the wear and tear on the door structure during long-term use.

3.The galvanizing process complies with the EU RoHS environmental protection standard. The surface zinc layer is uniform and dense, which can not only resist the rust risk in the humid climate of Europe and America but also withstand the long-term erosion of various disinfection detergents, taking into account both durability and environmental protection.

Food-grade silicone sealing strips (compliant with FDA 21 CFR 177.2600 standard) are equipped at the gaps between the door body, door frame, and the ground. When the door is closed, they fit tightly, effectively preventing dust, microorganisms, and other pollutants brought by air convection. The door body adopts a double-layer hollow structure, filled with high-density soundproof and heat-insulating materials inside. This not only meets the air isolation requirements of clean rooms but also addresses the energy consumption control requirements in Europe and America, achieving a dual guarantee of energy conservation and cleanliness.

It can be equipped with EU-certified infrared sensors and automatic door closers. The sensors are highly sensitive and their response speed meets European and American industrial safety standards, enabling contactless door opening and reducing the pollution risk caused by human contact. The closing force and speed of the door closer can be precisely adjusted to adapt to the usage requirements of different scenarios, ensuring both the airtightness of the door when it closes automatically and avoiding potential safety hazards caused by the door closing too quickly.

We are well aware of the high requirements of European and American customers for details and provide comprehensive customization services:

4.According to your workshop layout, we can customize opening methods such as single - door, double - door, and sliding doors. The surface of the galvanized steel sheets of the door frame and door leaf can be electrostatically sprayed as required to match the overall color of the workshop.

5.We support the installation of EU-standard observation windows (using anti - fog tempered glass), emergency escape devices, etc., to meet the personalized needs of different scenarios and ensure that the purification door seamlessly adapts to your production environment.

Choosing our purification doors not only guarantees quality compliance with European and American standards but also offers detailed designs optimized for the local market. We always focus on high quality and cost - effectiveness, providing reliable cleanliness solutions for European and American customers. We look forward to working with you to create a clean production future.

Our cleanroom doors stand out in three key aspects, meticulously engineered to meet the stringent demands of high-cleanliness environments such as pharmaceutical labs, electronics cleanrooms, and sterile food processing facilities:

1.Sturdy & Certified Structures: Fully CE and FDA-certified, our doors boast a robust build with 1.2MM galvanized steel frames—providing exceptional rigidity to resist warping under constant use—and 0.8MM galvanized steel door leaves that balance strength with lightweight maneuverability. This combination ensures long-term durability against frequent opening/closing cycles, accidental impacts from equipment or personnel, and exposure to harsh cleaning agents, all while maintaining structural integrity to uphold strict cleanroom standards.

2.Premium Hardware for Sterile Reliability: Every hardware component—from handles and hinges to fittings—holds separate CE certification and is crafted from high-grade 304 stainless steel. This material offers superior corrosion resistance, making it impervious to rust even after repeated sanitization with chemicals or high-pressure washing. Designed for heavy-duty use, the hardware ensures smooth operation over time, avoiding jams or wear that could compromise the door’s seal, and its non-porous surface prevents bacterial buildup—critical for maintaining sterile conditions.

3.Advanced Vision Panels with Hygienic Design: The integrated vision panel features 5MM tempered glass, delivering exceptional impact resistance to withstand daily collisions in busy environments. Its flush integration with the door leaf creates a seamless, gap-free surface, eliminating crevices where dust, microbes, or debris could accumulate—simplifying cleaning and reducing contamination risks. Additionally, a precision-engineered pressure balance hole in the panel equalizes air pressure between the door’s hollow interior and external environment, preventing glass distortion caused by temperature fluctuations or air flow changes, and preserving the door’s airtight seal to maintain stable cleanroom pressure.

Together, these features converge to deliver a reliable, hygienic, and long-lasting solution that not only meets but exceeds the performance requirements of critical cleanroom and sterile facilities.

A1:Surely yes. Mixed colors and models are acceptable in One 20GP or in one 40HQ we suggested 3-6 models.

A2:Yes,we can.But customer should send us drawing to check firstly,then we shall reponse you the correct drawing for production .

A3:For small sample,we can offer for free.For completely doors ,we have to charge some cost on actual situation. But we will refund the sample charge to you if you place bulk order next time.

A4: Delivery time: About 7-20days.

First we need know your specific door request and specs, then we issue the related solutions to meet your requirements. After that, we make the invoice and drawings for your approval. Once you approve the both, 50% deposit will be arranged and the production is started; after the order is finished, we take video or pictures to you, or you dispatch inspector here, then collect the balance before shipping.

A5:we stock American standard hollow metal door & frames as procedure in factory. When your order is special and need customerized , we need arrange that specially, just like project schedule, most of them need customerized by specific size, color, lock type, materials, etc. So, we can pick up wholesaler order or end user project order both.
